Nylon mesh is a cut-away backing. Cut-away backing is used on stretch fabrics. The cut-away backing helps support the fabric during and after the embroidery process. It is suitable for t-shirts, golf shirts, sweaters, sweatshirts, Lycra and spandex. Nylon mesh is softer than polyester backing and so better suited for children’s wear. It also will not show through light colored shirts. You can also double the layers of no-show if additional hold is required.
